I have a 2002 honda civic ex 5speed and have been stumped for a couple days now, new fuel pump new fuel filter, building some pressure in gas tank but still nothing coming out. Figured id take it apart for like the 5th time lol to see if i missed anything and i sure did. Theres a little brown retaining clip directly on top of the fuel pump that helps it stay into the cage that was just missing. I CANNOT FOR THE LIFE OF ME figure out what its called or what part number it is, anyone have knowledge or can point me in the right direction??

Tan locking ring right there
